Allan Corfield Structures (ACS) was initially established in early 2021 to provide structural engineering services to Allan Corfield Architects (ACA) clients. Led by our Technical Director, Chartered Structural Engineer and SER Certifier David Gallagher, ACS now offers a market-leading service for both ACA & external clients, inc a number of top Architects & MMC kit suppliers.

Since its inception, ACS has secured over 70 projects, and the team has grown to 9. We provide value from the early design stages by working closely with our clients and designers rather than as a traditional reactive engineering service. Our vast experience in Modern Methods of Construction, such as Timber frame, SIPS, and ICF are the reason we are the right choice for your project.

From early site feasibility studies on one-off homes or large-scale developments, our team can mitigate your risk, helping you understand what is going on, on your site.
